.To all whom it may concern:

Be it known that I, WILHELM ALETTER, a subject of the German Emperor, and a resi dent of Berlin, Germany, have invented certain new and useful Improvements in Self Acting Cooking Apparatus,

lowing 1s a specification.

This invention relates toso-called selfacting cooking or boiling apparatus in which1i the vessel containing the previouslyheate food is put into a chest or receptacle which is wholly surrounded by a bad conductor of heat. 1 I

- It has for its object to enable such apparatus to be used also for, baking or roasting purposes.

For this purpose the invention consists, essentially, in roviding the said chest or retii two stones i W on the apparatus is to be used andthe vessel containing the food to be boiled and baked or roasted is put between them into the chest.

The apparatus which is the object of the present invention is-represented in the accoinpanying drawings, in which- Figure 1 is a perspective external view; and Fig. 2 a vertical section, the inner parts being in pers ective view and somewhat separated one lTOlil another.

The ap )aratus consists of the chest or re ceptacle t ie double walls of *hich are filled in the well-known manner with a bad conductor of heat I). The said chest can be closed by a cover 0, having a hollow part on tering into thc hollow space of the'chest and being also filled with a bad conductor of heat. In the chest (1/ is contained the vessel d, which contains the food to be roasted or baked, and said vessel rests on a removable plate or disk '6, made 'of artificial or natural stone. On the top of the vessel d iron bands or girders f are hung, on which a second plate or disk g,

of artificial or natural stone, 1S put.

If the apparatus is to be used, the cover c is rernoved and the vessel (1, together with the plates e and g, are taken out of the chest at. The plates e and g are heated by means of an alcohol, gas, or other lamp or by any other source of heat. When the plates have be come rather hot, the vessel containing the food to be roasted or baked or cake) is put for about ten minutes on one of them,while it continues to be heated. Al

been previously hung on the up of which the fol- (roast, joint, pie,

ter sui'licient heating first the plate e is put on the inner bottom of. the chest, Then the "vessel (1 is placed on. it, and then the plate g is ut on the bands or girders f, which have er edges of said vessel, Then the chest is 0 need bythe cover 0 and left closed as long a time as is D GO-r essary for roasting or baking the food in an ordinary roaster "or boiler. Then it may be opened and the food taken out directly or at any time afterward.

I do not claimin general self-acting cooking apparatus surrounded with a bad conductor of heat, nor do I claim in'general the use of a heated plate with which the vessel is brought into contact withinthe chest, the

main feature otiny invention being the use of two plates or disks, which are made of stone and of which when heated. the one is laid. be low and the other above thevessel'containing the "food to be boiled, roasted, or baked.

I claim 1. An apparatus for automatically roasting or baking previously-heated food, consisting of a chest provided with alining of a bad conductor of heat, a vessel d into which the preheated food is (placed, girders hung onv the upper edge oi sa' vessel, and two plates of stone which are to be heated before they are put into the chest and which are arranged one immediately below said vessel (1 and the other supported upon the girders within said vessel.

2. An apparatus for automatically roastsisting of a chest lined with a bad conductor of heat, a cover having a hollow part entering the hollow space of the chest, and also filled with a bad conductor of heat, a vessel (1 intowhich the preheated food is placed, girders hung on the upper edge of saidyessel, and two plates of stone which are to be heated before they are put into the chest, and are arranged one immediately below and to support said vessel and the other supported upon the girders within said vessel.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. a r
